Chronic Kidney Disease

Chronic kidney disease involves a gradual loss of kidney function. Your kidneys filter wastes and excess fluids from your blood, which are then removed from your urine. Advanced chronic kidney disease can cause dangerous levels of fluid, electrolytes, and wastes to build up in your body. In the early stages of chronic kidney disease, you might have few signs or symptoms. You might not realize that you have kidney disease until the condition is advanced.
